LONDON, United Kingdom, September 14, 2026 / Newsfile / Meridian Mining plc (LSE: MNO) (TSX: MNO) (FSE: N2E0) (Tradegate: N2E0) (OTCQX: MRRDF) (“Meridian” or the “Company”) is pleased to announce its inclusion in the VanEck Junior Gold Miners ("GDXJ") Exchange Traded Fund (“ETF”) following the GDXJ's quarterly review and rebalancing announced on September 11, 2026, effective at the close of markets on September 18, 2026.

The GDXJ is the leading global ETF providing investors exposure to precious metals through junior mining equities. The ETF tracks the most liquid small and mid-capitalisation companies primarily involved in the mining and development of gold and silver assets.

Gilbert Clark, CEO, comments: "Inclusion in the GDXJ, a globally recognised ETF is a significant milestone, reflecting Meridian’s increased visibility as an investment opportunity. This is a testament to the progression and de-risking of the advanced staged Cabaçal Project. We believe inclusion in the GDXJ index will further improve trading liquidity increasing access to a wider universe of institutional and retail investors seeking exposure to the gold sector and that benchmark against the GDXJ.”
